In mile there are 63360 inches.
The number of inches in a mile is equal to the number of inches in a foot times the number of feet in a mile
We multiply 528 by 12 and add one zero to the right of the result.
Use vertical form to perform the multiplication.
So. 12 × 5280=63360
∴ 5280/6336
= 1056
The number of inches in a mile = 12 × 5280
We multiply 528 by 12 and add one zero to the right of the result.
Use vertical form to perform the multiplication:
528 × 12 = 1056
1056 + 5280 = 6336
So, 12 × 5280 = 63360 miles
Therefore, in mile there are 63360 inches.

Subtracting a number is the same as adding its additive inverse. For which elevation do we need to find the additive inverse? What is the additive inverse of that elevation?
Yes subtracting a number is the same as adding its inverse. We have to find the additive inverse of a function.
What is additive inverse?The additive inverse of a number is the number which when we add to the number results zero.
How to find additive inverse?Complex numbers are made up of both real and fictitious numbers. A + iB, where A is the real number and B is the imaginary number, is a complex number.
The additive inverse of A + iB should now be a value that, when added to a given complex number, produces the result zero. It will therefore be -(A + iB).
Suppose we have to find additive inverse of 5.
Let the additive inverse of 5 be x.
So,5+x=0
x=-5
So the additive inverse of 5 is -5.
Hence to find additive inverse of a positive number we have to just put a negative mark and for a negative number we have put positive mark in front of the number.

Answer:
252 m^2
Step-by-step explanation:
The equation for surface area in a rectangular prism is SA = 2 (lh +wh + lw ).
So when we plug in the numbers inti the equation we do SA = 2(12×3 + 6×3 + 12×6)
FOLLOW P.E.M.D.A.S (parentheses, exponents, multiplication, division, addition, subtraction)
we get SA = 2(36 + 18 + 72)
then we multiply 2, by each of the numbers.
SA = (72 + 36 + 144)
Add them together and you get
SA = 252

Write an expression that represents the height of a tree that begins at 8.4 feet and increases by 3.8 feet per year. Let's describe the number of years.
Answer: 8.4 + 3.8y
Step-by-step explanation: The expression is 8.4 + 3.8y ( y represents the amount of years multiplies by 3.8 or the amount grown per year )
Unless there is a total of height or the amount of years there is no way to complete this problem because there is an infinite number of possibilities.

if you test for the for the mean of the differences in a paired t-test, there are how many degrees of freedom?
There is zero or no degree of freedom in the mean of the differences in a paired t-test.
For the paired t-test, we need two variables. One variable defines the pairs for the observations. The second variable is a measurement. Sometimes, we already have the paired differences for the measurement variable. Other times, we have separate variables for “before” and “after” measurements for each pair and need to calculate the differences.
We also have an idea, or hypothesis, that the differences between pairs is zero. It is also known as the dependent samples t-test, the paired-difference t-test, the matched pairs t-test and the repeated-samples t-test.

A two digit number is such that sum of the ones and tens digit is 10.If the digits are reversed, the new number formed exceeds the original number by 54. Find the new number
Let the tens digit of the original number be x and the ones digit be y. The original number is 10x + y, and the new number formed by reversing the digits is 10y + x.
Since the new number exceeds the original number by 54, we can set up the equation:
10y + x = 10x + y + 54
9x - 9y = 54
x - y = 6
Since x and y are both digits, they must both be integers. The only solution to this equation that satisfies this condition is x = 8 and y = 2.
Therefore, the original number is 82 and the new number formed by reversing the digits is 28. This is the new number.

Dean Willis earns $315.75 per weck. The Social Security tax rate is 6.2% and Medicare tax is 1.45% of gross pay. How much is the deduction from his pay check for Social Security and Medicare?
The total deduction from Dean's paycheck for Social Security and Medicare is $24.11.
What is a percentage?
A percentage is a way of expressing a number as a fraction of 100. It is often used to express a proportion or a ratio, and is denoted by the symbol "%".
To find the deduction from Dean's paycheck for Social Security and Medicare, we need to calculate the total amount of tax that he owes based on his gross pay.
First, we can calculate the Social Security tax by multiplying Dean's gross pay by the tax rate:
Social Security tax = $315.75 x 6.2% = $19.54
Next, we can calculate the Medicare tax by multiplying Dean's gross pay by the tax rate:
Medicare tax = $315.75 x 1.45% = $4.57
To find the total deduction from Dean's paycheck, we can add the two amounts:
Total deduction = $19.54 + $4.57 = $24.11
Hence, the total deduction from Dean's paycheck for Social Security and Medicare is $24.11.

A lake fishing map is laid out on a coordinate plane with each unit equal to 1 mille. The boat is launched from the point (7,0) and goes to point (7.-7) to fish. From there, the boat
travels to (0, -7) to fish and then goes back to the launch point.
Determine the total number of miles traveled. Round to the nearest whole number.
•10 miles
•12 miles
•14 miles
•24 miles
The total number of miles traveled by the boat, found using Pythagorean Theorem, rounded to the nearest whole number is about 24 miles
What does the Pythagorean Theorem state?Pythagoras theorem indicates that the square of the hypotenuse side of a right triangle is the same as the sum of the squares of the legs.
The coordinates of the location of the boat as goes to fish are;
The coordinate of the point at which the boat is launched = (7, 0)
The coordinate of the point at which the boat goes to fish = (7, -7)
The coordinate of the location the boat then travels to in order to fish = (0, -7)
Let A represent the point (7, 0), and let B represent the point (7, -7), and let C represent the point (0, -7), we get;
A(7, 0), B(7, -7), C(0, -7)The length of segment AB = 0 - (-7) = 7
Length of segment BC = 7 - 0 = 7
The x and y-coordinates of the points A and C are different therefore, the length of the segment AC can be found using the distance formula used for finding the distance between two points on the coordinate plane (a form of the Pythagorean Theorem) as follows;
d = √((x₂ - x₁)² + (y₂ - y₁)₂)
The distance between the points A(7, 0), and C(0, -7), is therefore;
Length of segment AC = √((0 - 7)² + (-7 - 0)²) = 7·√2
The total number of miles the boat traveled is therefore;
Total distance traveled = AB + BC + AC
Therefore;
Total distance traveled = 7 + 7 + 7·√2 ≈ 23.889 ≈ 24
